Abstract

A control and safety device for burners of gas appliances is described, in particular for domestic use, capable of fulfilling a plurality of cooking functions, comprising all the known elements for their operation, including safety means which are actuated through an axial control given by a shaft of a cock controlling the burner operation.
The main feature of the invention consists in that means (6, 9, 11) are provided for the safety activation, which give the axial control to said shaft through the rotation of the control knob of the cock also when said knob is not directly connected to said shaft, by converting at least a part of the rotary motion of the knob in an axial motion.
